Declaration of conformity for products with Model EPDs

The European Federation of Concrete Admixtures Associations (EFCA) has developed Model Environmental Product Declarations (Model EPD) for six categories of admixtures. These model EPDs have been verified as being in compliance with EN 15804 and ISO 14025 and published by the independent Institute for Construction and Environment in Germany (IBU). Additionally, the Model EPDs are based on the established Product Category Rules (PCR) for Concrete Admixtures which are currently the only generic PCRs that exist for this product type. The Model EPDs are also available for download from the EFCA website.

Sika is a member of Fachverband Schweizerischer Hersteller von Betonzusatzmitteln (FSHBZ) which is a national association member of EFCA. This gives the company the right to declare that a specific EFCA Model EPD applies to the named products listed below, by using an IBU-approved guideline procedure, to confirm that any particular product is within the scope of a specific product category Model EPD. This means that the life cycle assessment data and other content of the Model EPD apply to these named products and may be used for LEED v4 sustainability assessment of the construction products and construction projects, in which they are used.

2. Product

2.1 Product descriptionAdmixtures are liquid or powdery agents that are introduced in small amounts (< 5% by mass of the cement content) to concrete while it is being mixed and that enhance the properties of the fresh and/or hardened concrete.Plasticisers and superplasticisers are admixtures which reduce the water content of mixed concrete without detriment to its consistency or enhance its slump with or without change to the water content or cause both effects simultaneously. They can also display a retarding effect when used as combination products.The results of the Life Cycle Assessment provided in this declaration have been selected from the product

with the highest environmental impact (worst-case scenario).2.2 ApplicationConcrete admixtures are used as constituent materials for the production of concrete, mortar and grout (unreinforced concrete, reinforced and prestressed concrete, site-mixed and ready-mixed concrete, precast concrete). Their application should be in line with the manufacturer’s technical documents and Declaration of Performance.

2.3 Technical DataPlasticisers and superplasticisers must comply with the general requirements of /EN 934-1:2008/ and the additional requirements of /EN 934-2:2009+A1:2012/.

2.4 Application rulesFor products placed on the market in the European Economic Area (EEA) the Construction Product Regulation (Regulation (EU) No 305/2011) applies /CPR/. Outside of the EEA, the corresponding national regulation applies. Admixture products placed on the market under the CPR require a Declaration of Performance and CE marking taking consideration of /EN 934-2:2009+A1:2012/. For the application and use of the products the respective national provisions apply.

2.5 Delivery statusPlasticisers and superplasticisers are usually supplied in liquid, paste or powder form in containers made of steel or plastic.Typical container sizes are canisters containing approx. 25 kg, drums with approx. 200 kg or Intermediate Bulk Containers (IBC) with 1000 kg. The containers are shipped on wooden pallets.For larger applications, loose deliveries in tank trucks with a capacity in excess of 1 tonne are also used.

2.6 Base materials / Ancillary materials Plasticisers and superplasticisers essentially contain ether lignosulphonate, naphthalene sulphonate, melamine sulphonate and polycarboxylate/polycarboxylic or mixtures thereof. Defoaming agents and preservatives are added as minor components and auxiliaries.Active substance concentration lies between 10 and 40% by mass. The typical dosage of plasticisers lies between 0.2 and 0.5% by mass in relation to the cement weight. The typical dosage of superplasticisers lies between 0.4 and 2.0% by mass in relation to the cement weight. The products covered by this EPD typically contain the following proportions by mass of constituent materials and auxiliaries referred to:Lignosulphonate*: max. 35%Naphthalene sulphonate*: max. 30%Melamine sulphonate*: max. 45%Polycarboxylate*: max. 35%Additives: max. 5%Water: approx. 55 - 75%*Solid contentThese volumes are average values and the composition of products complying with the EPD can deviate from these concentration levels in individual cases.Note: For companies to declare their products within the scope of this EPD it is not sufficient to simply comply with the product composition shown above. The application of this EPD is only possible for member companies of EFCA’s member associations and only for specific formulations with a total score below the declared maximum score for a product group according to the associated guidance document.Small volumes (< 0.5% by mass) of biocides with functional chemical groups for example isothiazolinones or dioxahexane are used as preservatives in concrete admixtures during storage.More detailed information is available in the respective manufacturer's documentation (e.g. product data sheets, safety data sheets).Unless indicated on the safety data sheet, concrete admixtures do not contain any substances in concentrations of more than 0.1% which are included in the list of Substances of Very High Concern (SVHC) for inclusion in Annex XIV of the REACH regulation.

4 Environmental Product Declaration EFCA – Concrete admixtures – Plasticisers and Superplasticisers

No flame retardants are used in concrete admixtures.

2.7 ManufactureConcrete admixtures are usually manufactured by mixing ingredients together in batch mode and filling containers for dispatch. The process follows quality standards outlined in /EN 934-6:2001+A1:2005/.

2.8 Environment and health during manufacturing

As a general rule, no environmental or health protection measures other than those specified by law are necessary.

2.9 Product processing/InstallationDuring concrete manufacture, concrete admixtures are usually added along with the mixing water or included in premixed concrete.

3. LCA: Calculation rules

3.1 Declared UnitThis EPD refers to the declared unit of 1 kg concrete admixture with a density of 1-1.6 kg/l in accordance with the IBU PCR 07.2014 Part B for concrete admixtures. The results of the Life Cycle Assessment provided in this declaration have been selected from the product with the highest environmental impact (worst-case scenario). Depending on the application, a corresponding conversion factor such as the density to convert volumetric use to mass must be taken into consideration. 3.2 System boundaryModules A1, A2 and A3 are taken into consideration in the LCA:- A1 Production of preliminary products- A2 Transport to the plant- A3 Production incl. provision of energy, production of packaging as well as auxiliaries and consumables and waste treatmentThe Declaration is therefore “cradle-to-gate”.

3.3 Estimates and assumptionsFor this EPD formulation and production data defined by EFCA were considered. Production waste was assumed to be disposed of to landfill without credits as a worst case.An average of plastic containers and wooden pallets was considered in the LCA.

3.4 Cut-off criteriaAll raw materials submitted for the formulations and production data were taken into consideration.The manufacture of machinery, plant and other infrastructure required for production of the products under review was not taken into consideration in the LCA. Transport of packaging materials is also excluded.

3.5 Background dataData from the GaBi 6 data base was used as background data.

3.6 Data qualityRepresentative products were applied for this EPD and the product in the group displaying the highest environmental impact was selected for calculating the

5 Environmental Product Declaration EFCA – Concrete admixtures – Plasticisers and Superplasticisers

LCA results. The data sets are no more than 4 years old.Production data and packaging are based on details provided by the manufacturer. The formulation used for evaluation refers to a specific product.The data quality of the background data is considered to be good.

3.7 Period under reviewRepresentative formulations were compiled by EFCA in 2011.

3.8 AllocationNo allocations were applied for production.

3.9 ComparabilityBasically, a comparison or an evaluation of EPD data is only possible if all the data sets to be compared were created according to /EN 15804/ and the building context, respectively the product-specific characteristics of performance, are taken into account.

4. LCA: Scenarios and additional technical information

In accordance with the IBU PCR 07.2014 Part A, no scenarios are indicated as only Modules A1-A3 are declared.

6. LCA: Interpretation

When considering upstream production and transport of pre-products as well as manufacturing of the concrete admixture (modules A1-A3), the main driver of impacts in all categories is production of pre-products (module A1).In the categories of ozone depletion potential (ODP), renewable primary energy demand (PERT), radioactive waste, and acidification potential (AP) a fairly important contributor is the European electricity grid mix, which also has minor influence on photochemical ozone creation potential (POCP).The plastic packaging of the concrete admixture also makes a minor contribution, especially to abiotic depletion potential for fossil resources (ADPF), photochemical ozone creation potential (POCP), and

non-renewable primary energy demand (PENRT), as do wooden pallets (in the case of PERT).Generally, treatment of production waste has negligible influence on results in all impact categories for this product type.
